Is there a condition where a recipe would call for margarine for a specific
reason where it would be better to use than butter? If the two are
interchangeable, why not say "margarine or butter"? I use safflower oil
where it calls for butter in crêpes and I don't notice much of a diff.

Tonight I had a recipe for an apple curry sauce for pork chops which
required 1/4 cup of margarine. I used butter instead, being the hard-nosed
rebel that I am.

So, any ideas?
